To all wiz/0m 25mm/:concern: y

Be it known that `LfTiroi/Ins BROWN, a

`subjectof Great BritaimQreSiding :at No.

113 Fenchurch `street,"inthe city ofLondon,

have invented a new and usefulImprovement in Sailingand otherVessels Produced 1 `by a` New Form and Arrangement of the `Itiding-Bitts; andI do` hereby declare that the following isa full and. exact description thereof, reference being had to `the accompanyingi drawings, making a part` of this` .specication,l Figure `1` lbeing a topview of a section of a deckof a vessel with one of `my improved riding-bitts combined therewith; Fig.` 2, a vertical section in the line a a of Fig. 1;` Fig. 3, af vertical sectionin the line Y)` b of `Fig.` 1, and Fig. 4 a ver- 1 tical section in the linewxof Fig. land eX- `"the figures. n "A vessels- `riding-bitts have heretofore `3 n n b i 1 hibitinga front elevation of my improved riding-bitt. b .b y

Similar-letters indicatelike parts in all been made of strongwwooden shafts, or

bea-ms, which passthrough the deck `and b *have their lower .endssecured to the deck t b below; the portionsfof `said shafts which rise abovethedeck, and form the ridingy bitts, beingprotected by metallic casngs. 3 30` Thefollowing` disadvantages attend the nuse of the aforesaid form and arrangement `of `riding-bitts,` viz:` First,.the very great strain exertedyby` the cable upon the said bitts, )as it is drawn around them, renders z it `impossible to prevent their descending j shafts from workingginthe` deck, and consequently` producingileaky joints between them and the deck?, and," second, the descendb ing shafts `of the saidqriding bitts, itake up much valuable space between decks.` b My improvement in `riding-bitts, `consists `in making themof metallic tubes 0, c, which` chave sufciently broadanges d', d, at their y lower ends toenable` them` to rest firmly upon the deck; the said tubes being` secured `over openings in the deck, by means `of a suitable number of bolts g, g, passing through their flanges into, (or secured to platesV passing beneath,) the deck beams z, h, and by lugs e, e, which descend from the under side ofthe said flanges into recesses formed in the deck. b

p The advantages arising from the use of my improvedffform and arrangement of a vessels riding-bitts are as follows, viz: irst,` the openings f, in ,the deck-within and' below theiinner diameter of the bittsallow light and air to pass through the deck to the space between decks in fair weather and in foul weather, the covers y', which are then placed over the tops of the bitts, may have thick pieces of glass inserted in them, for the purpose of allowing light to pass below` at all times; second, the joint between thebase of the bitts and the deck, `can be made perfectly water tight. much valuable space is saved between decks, by securing the bitts entirely to a single deck. b

The normans ,70, le, may be combined with And third-` the riding bitts in the manner represented in thedrawings, or in any other that may be deemed expedient.

`What I claim as my invention and desire to secure by Letters Patent, is-

H The tubular metallic `riding bitts, when `j. entirely secured to a single deck of a vessel and arranged substantially in the manner' and for the purpose herein'set forth. y

In witness that the aboveis a true speci`` ication of my hollow metal self supported. subscribe Ventilating riding bitt I do hereby my name 1n presence of witnesses. v p THoMAsBRoWN.
